Fix Oppo F15 CPH2001 Download Not Completed Error (Oppo_Custom.bin Solution)

If you’re flashing your Oppo F15 CPH2001 (MTK device) and facing a “Download not completed” error in SP Flash Tool or MSM Download Tool, you’re not alone. This issue usually happens due to a corrupted or mismatched Oppo_Custom.bin file inside the firmware package. Don’t worry — this guide will show you how to fix it step-by-step.

What Causes the “Download Not Completed” Error?

This problem typically appears when:

• The Oppo_Custom.bin file is incompatible with your current device region or variant.
• The firmware was interrupted during the flashing process.
• You’re using an outdated or modified flash tool.
• The scatter file doesn’t correctly reference the custom partition.

Such mismatches can prevent proper flashing of the custom.img / Oppo_Custom.bin partition, resulting in an incomplete firmware installation.

Tools You’ll Need

Before fixing the error, make sure you have these ready:

Step-by-Step Solution

Step 1: Download Correct Firmware

Go to MobiFirms.com → Oppo Firmware → Oppo F15 CPH2001, and download the official tested firmware matching your build version. Always avoid mixed-region firmware (e.g., India firmware on a Nepal variant).

Step 2: Replace Oppo_Custom.bin

• Extract the firmware folder.
• Locate and delete the old Oppo_Custom.bin file.
• Copy the fixed Oppo_Custom.bin (from MobiFirms fix file package) into the same directory.

Step 3: Load Scatter File

• Open SP Flash Tool.
• Click Choose Scatter File → select MT6765_Android_scatter.txt.
• The tool will automatically list all partitions.

Step 4: Uncheck Preloader

Uncheck preloader to avoid bricking your device. Only flash system, vendor, userdata, and custom partitions.

Step 5: Start Flashing

Click Download, connect your phone in power-off state, and wait for the flashing process to complete.
Once done, you’ll see a green check mark ✅.

After Flashing

• Reboot your device.
• First boot may take 5–7 minutes — this is normal.
• Check IMEI and network; if missing, repair using Maui Meta or Modem Meta Tool.

Pro Tip

If the error still occurs, try renaming the fixed file to match the firmware structure exactly (e.g., Oppo_Custom.bin → custom.img). Also, use Firmware Upgrade mode instead of Download Only for cleaner flashing.

Conclusion

Fixing the Oppo F15 CPH2001 Download not completed error is simple once you replace the faulty Oppo_Custom.bin with a tested one. Download the 100% working fix from MobiFirms.com and safely restore your device without errors.
